This invention relates to locks, and particularly to a lock of the coin controlled type. It is an object-of this invention to produce invention, the money required is supposed to be a half-dollar coin, although obviously,'the

device can be proportioned so that the. tripping mechanism could be made to operate in v conjunction with coins of other diameters and sizes.

- It is a further object of this invention to provide novel meanswhereby the shackle of the lock will be retainedin locked positionby instrumentalities which will also serve-t guard against the escape of the coin after the'lock has been manipulated to release the object which it secured, so that by this invention, a lock may be applied to a device for securing an: automobile or any other.

property, and when the property is reclaimed by the insertion of thecoin of the required denomination and the lock is manipulated to release the property, the lock becomes effective to retain the coin against intended or accidental withdrawal.

It is furthermore an object to produce a lock of this character comprising comparatively. few and inexpensive parts.

W'ththe' foregoing and other objects view, the invention consists in the details of construct-ion, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed. V In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in 1whicl1- Figure 1 illustratesa view. in elevation of the exterior of a lock embodying the invention; M Figure 2 illustrates a-sectional view thereof with the locksecured in its stage of manipulation; r F igure3 illustrates a sectional View showing the parts in the second stage of manipu- I .7 p

In the present embodiment of the invention, a lock casing 10 is provided having-a cavity in its inner face for the operating .mechanisms, to be presently explained, and the casing may have any appropriate face plate 11, and these parts may be secured to gether in any appropriate way by rivets or the like. One end of the casing has agseat 12 for an end 13 of the shackle 14, whereas the opposite end of the shackle reciprocatesin an opening 15 of the casing and extends downwardly into the cavity at one side. or edge thereof. The casing "has a rib 16 that stands in spaced relation to the inner wall l7, and this forms a way in which an extension 18 of the shackle is slidable. The extension has, an annular shoulder19 which serves to'gu-ide the shackle in the cavity, and the said shoulder is engaged by a flange .20 of the rib 16, wherebythe axial movement of the shackle is limited.- i

A, spring 21 is seated in the cavity and encircles the extensionof the shackle.v The spring bears against the shoulder and exerts pressure to move. the shackle outwardly and to retain the shoulder in engagement with the flange when the device is unlocked. The shackle is .also provided with a beveled surface 22 terminating in a shoulder28 to be engaged bythe end 24 of a'dog 25, which dog is pivotally mountedon a stud 26 within.

the casing. The dog serves to hold. the

shackle against movement when it isIin-envgagement with the shoulder, although the dog will be manipulated to releasethe shackle, as will presently appear. a

k spring 27 is anchored to the dog and it bears, against an inner wall of the cavity at the top thereof,-as shown in Fig. 3, and this spring is effective, under certain conditions,

will engage'the shoulder of the shackleto secure the lock. An arm 28, preferably of relatively rigid character compared with the spr g 27, is als a h red tn the d g, and

perspective view of the r shackle.

the said arm has a surface 29 which is adapted to be engaged .by a coin 30 when the lock is to be released and the coin is to be secured in the lock, it being the intention of the inventors that the arm shall be in the path of travel of the coin in order that the pressure of the coin on the arm will overcome the tension of the spring 27 and move the dog on its pivot to disengage the said dog from the shoulder of the shackle.

As a'means for manipulating the coin, a yoke 31 is provided and it is slidable in the lower end of the lock casing and itvis of a size that will fit between the rib- 16 and the opposite inner wall of thecasing. The yoke or stirrup has a shoulder 32 at one side adapted to be engaged by the shoulder of the dog after the coin has been inserted and has swung the dog from engagement with the Figure 3 shows the dog locked to the yoke and retaining it in position to hold the coin secure in the casing. When the coin is to be released, a key 33 may be manipulated to force the dog from engagement with the yoke and the yoke will therefore be permitted to slide outwardly to release the coin.

The yoke ispressed normally outwardly by a spring 34 on a post 35 and the said post extends into an aperture 36 in the yoke. The spring 34 bears against the inner end of the yoke and normally exerts pressure on it to force it outwardly so that after the dog dis-.

engages the yoke, the spring causesthe ejection or partial ejection of the coin. The yoke is limited in its movement by reason of the projection 39 on the yoke engaging a stop {l0 on the case.

In Fig. 2 when the lock is locked to secure property, there is a clearance 37 between the coin seat of the yoke and the lower end of the lock casing, .through which the coin is introduced into the casing, and when so introduced, the coin is forced further into the casing by pressure on the yoke,'which moves the yoke inwardly and forces the coin against the arm to overcome the tension of the spring 27 in order that the dog will be manipulated. To facilitate the introduction of the coin, the surface 38 of theyoke is rounded and it will therefore cam over this rounded surface as it is pressed into the lock casing From an inspection of the drawing and the foregoing description, it will be apparent that after the lock is secured to guard property, it cannot be manipulated by the key, since any pressure of the key on the dog will more firmly seat the dog in engagement with the shackle, and it is only by imparting movement to the dog through pressure applied on the arm that the dog will be caused torelease the shackle.

2. A coin controlled lock consisting of a lock case, a shackle therein, a detent for holding the shackle in locked position, means associated with the detent and operative by pressure of a coin to disengage the detent from the shackle, means for exerting pressureon the coin to operate the detent, means whereby the detent engages the coin moving means and holds it against movement to retain the coin in the lock, andmeans for operating the'shackle when released by the detent.

3. In a coin controlled lock, a case, a shackle having one end projecting therein, a dog for engaging the shackle, means for oscillatably mounting the dog, a spring associated with the dog for holding it normally in engagement with the shackle, a coin engaged element in the case associated with the dog,- means for forcing a coin into the case againstthe said element for moving the dog, coacting means between the dog and the last mentioned means for retaining said last mentioned means in position to retain the coin in the case, said dog being adapted to be released by a key.
